Product information VAV-Compact KNX

A pressure sensor, digital VAV controller and damper actuator all in one, providing a compact solution with a communications capability for pressure-independent VAV and CAV systems in the comfort zone• Communication via KNX (S mode)• Conversion of sensor signals• Service socket for operating devices

Brief description

Application The VAV-Compact has PI control characteristics and is used for pressure-independent control of VAV units in the comfort zone.

Pressure measurement The integrated D3 differential pressure sensor is also suitable for very small volumetric flows. The maintenance-free sensor technology enables versatile applications in the comfort zone: in residential construction, offices, hospitals, hotels, cruise ships, etc..

Actuator 2 different actuator variants (5 or 10 Nm) are available for different VAV unit structures.

Control function Volumetric flow (VAV-CAV) or Open-Loop (for integration in an external VAV control loop).

VAV – variable volumetric flow Demand-dependant setting of volumetric flows min … max on a modulating reference variable via KNX, e.g. room temperature / CO2 controller, DDC or Bus system, for energy-saving air conditioning in individual rooms or zones.

DCV – Demand Controlled Ventilation In higher-level KNX system, for example with integrated optimiser function.

Type of action The actuator is fitted with an integrated interface for KNX (S mode), it receives the digital positioning signal from the KNX system and returns the current status.

Converter for sensors Connection option for a sensor (active sensor or switching contact). In this way, the analogue sensor signal can be easily digitised and passed along to KNX.

Parameterisation The factory settings cover the most common applications. As desired, individual parameters can be adapted for specific systems or servicing with a service tool (e.g. ZTH EU).

Communication parameters The VAV Compact is equipped with an integrated interface for KNX (S MODE). The VAV controller can be connected with all KNX devices that have corresponding data points available.

Operating and service devices Service tool ZTH, PC-Tool service socket: locally pluggable or via PP connection.

Electrical connection The connection is made with the integrated connection cable.

Sales, mounting and setting VAV-Compact will be mounted by the VAV unit manufacturer (OEM), the application will be set and calibrated accordingly. The VAV-Compact is sold exclusively via the OEM channel for this reason.

As an alternative, they can be read as total fault status.

Sensor value The representation of the sensor value is dependent on the parameterization.See section "KNX parameters – Sensor"



KNX parameters – General

System altitude [m] The specification of the system altitude increases the precision of the volumetric flow control.Values range: 0 … 3000 mFactory setting: 500 m

Setpoint with bus fail A setpoint can be defined for cases of communication interruption.Values range: None (last setpoint) Open Closed MidFactory setting: None (last setpoint)The monitoring of the communication takes place for the KNX group objects Setpoint and Override control. If none of the objects is written within the parameterised monitoring time, the bus fail position is set an signalled in the Service information (Bit 9).

Bus monitoring time [min] Monitoring time for the detection of a communication interruption.Values range: 1 … 120 minFactory setting: –

Difference value for sending the actual values [%]

Actual values (position, volumetric flow) are transferred at the time of a value change insofar as these change by the parameterised difference value. If the relative value changes by the difference value, not only the relative actual value but also the absolute actual value are transferred.Values range: 0 … 100%Factory setting: 5%The transfer is deactivated with 0% in the event of a value change.

Repetition time [s] Repetition time for all position, volume and sensor actual values. Status objects are not transferred except with a change.Values range: 0 … 3600 sFactory setting: 0 = no periodic transmission

KNX parameters – Sensor

Sensor type The input Y/3 can be used to connect a sensor. The sensor value is digitised and made available as KNX communication object. Values range: No sensor Active sensor (0 … 32 V) Switching contact (0 / 1) Humidity sensor (0-10 V corresponds to 0 – 100%) Air quality sensor CO2 (0-10 V corresponds to 0 – 2000 ppm)Factory setting: No sensorA switching to Y/3 is treated as local override switching in the absence of sensor parameterization.

Difference value for sending the sensor value The sensor value is transferred at the time of a value change insofar as this changes by the parameterised difference value.Values range: 0 … 65,535Factory setting: 1The transfer is deactivated with 0 in the event of a value change. Without value change, the sensor value is sent because of the repetition time.

Output(for sensor type "Active sensor")

Only for "Active sensor" sensor typeValues range: Sensor value mV (DPT 9.020) Sensor value scaled (DPT 7.xxx) Sensor value scaled % (DPT 5.001)Factory setting: –For "Sensor value mV", the measured voltage is made available without processing. In the case of the scaled sensor values, a linear transformation can be defined with two points.

Polarity(for sensor type "Switching contact")

The polarity can be defined for the sensor type "Switching contact".Values range: Normal InvertedFactory setting: –



Work procedures

Product database The product database for the import in ETS4 or higher is available at the Belimo website www.belimo.eu (Download Centre)

Setting physical address The programming of the physical address takes place by ETS and the programming button on the device. If the programming button is not accessible or accessible only with difficulty, then the address can be set using a point-to-point connection: "Overwrite physical address: 15.15.255"As a third possibility, the physical address can be programmed on the basis of the KNX series number (e.g. with Move’n’Group). The KNX series number is place on the device in two versions. One sticker can be removed for adhesion on the commissioning journal, for example.

Firmware upgrade The KNX firmware of the device is updated automatically with the programming of the application program insofar as the product database has a more recent version. The first programming procedure takes somewhat longer in such cases (>1 min).

Resetting to KNX factory settings If necessary, the device can be reset manually to the KNX factory settings (physical address, group address, KNX parameters).For the reset, the programming button on the device must be pressed down for at least 5 s during start-up.

Explanations 1) Access only on operating level 22) CAV setting for MP/MF type3) within the mechanical limit.4) The first time the supply voltage is switched on, i.e. at the time of commissioning, the actuator carries out an adaption, which is when the operating

range and position feedback adjust themselves to the mechanical setting range. The actuator then moves into the required position in order to ensure the volumetric flow defined by the positioning signal.
